Interstitial Emphysema and Pneumothorax Associated with the Use of a Modified Non-Rebreathing Valve

Increase of intrathoracic pressure to a dangerous level is probable when some modified non-rebreathing valves are used under certain circumstances.

A description of a near fatality due to bilateral pneumothorax and massive interstitial emphysema is presented, which illustrates this danger.

Unfamiliarity with some apparatus which may be completely closed intermittently by an automatic device may be particularly dangerous with children who are intubated and have increased compliance of the pulmonary system.
